      Yes. It throws the same error message as above at the bottom on the page.

      As far as packages are concerned I have only two running and the live status generally shows ram usage at around 30%. Open VPN is available but rarely connected.

        Hello!

        By default, only some of the feeds in the pfb PRI1 group are enabled. The PRI2 group (alienvault feed) is considerably larger and may take more memory (?). Maybe try disabling the PRI2 group?

          Ok Disabling that PRI2 group has prevented the error message from appearing. Do you consider that was the cause of the failure for rules to take effect too ?

            Hello!

            I dont know if that would cause the rule change issue you were seeing.

            I had to increase the Firewall Maximum Table Entries setting to get PRI2 to load.

              It almost certainly was the cause. Is the ruleset cannot load the previous loaded rules continue to be used.

              In this case the ruleset is loaded correctly at boot because the pfBlocker table has not yet populated but any change after it has pulled in that data could not be applied.

              The SG-1100 has limited available RAM. Do you have anything else running that uses significanlt memory? Snort, Squid etc?

                Did anyone ever figure this out, other than disabling PFBlocker? I have the default Table count, but it seems that it is not even being all used? Below is taken from pfblockerng.log.

                  Are you running 2.4.5p1? What hardware are you running on?

                    @Be-Bop-Bo , You need to sign up (free account) on maxmind.com/en/geolite2/signup. Once you have Maxmind License Key;

                    • go to Firewall > PfblockerNG > IP > MaxMind GeoIP configuration and insert your key.
                    • run an update Firewall > PfblockerNG > Update > Run.
                    • then select the rules by highlighting them. Firewall > pfblockerng > ip > geoIP > edit > Highlighted all ipv4/6 countries. After that you need to run an update again.
                      That's it.

                      @stephenw10 - Sorry I guess I am not, I am one back at 2.4.5, not _p1. I am running a SG-1100, though. I have another device that is a full 1U Atom computer and obviously I do not have this issue. Is it based on the total RAM available? The SG-1100 currently sits at around 68%-72% utilized.

                      If I disable everything else and only go with the AV reputation list, I continue to get the errors about memory allocation. That seems weird to me as it does not seem to have enough items to fill the table allocation.

                        @AKEGEC -I do have some Geo-IP restriction working with a free MaxMind account, but wanted a bit more intelligent based blocking.

                          You need to update to 2.4.5p1. In 2.4.5 you will be hitting this:

                            @stephenw10 From all accounts you are dead on. I did this late last night and I have not receive any alerts in nearly 12 hours, other than immediately after the reboot.

                            Much appreciated!

                              Go to Firewall:System -> Advanced -> Firewall & NAT: Firewall Maximum Table Entries value of "800000"
